Fluid jet injector device for a yarn bulking apparatus

ABSTRACT

A FLUID JET INJECTOR DEVICE FOR USE WITH YARN BULKING APPARATUS AND OTHER APPARTUS AND ADAPTED TO SEPARATE THE FILAMENTS OF A YARN BUNDLE AND TO INCREASE DRAG TENSION ON THE YARN SO AS TO ASSURE CONSTANT SELF-FEEDING OF THE YARN FROM ITS SOURCE TO AND THROUGH THE DEVICE, TO RAISE THE TEMPERATURE OF THE YARN TO A CRIMP RECEPTIVE CONDITION, AND TO CONVEY THE YARN TO THE BULKING APPARATUS. THE HOUSING OF THE INJECTOR DEVICE HAS A PASSAGEWAY THROUGH WHICH COMPRESSIBLE FLUID, PREFERABLY HEATED, AND THE YARN TRAVEL, AN ANVIL AGAINST WHICH THE COMPRESSIBLE FLUID AND YARN COLLIDE AND REBOUND CAUSING INCREASED FILAMENT SEPARATION AND HENCE INCREASED DRAG TENSION, AND AN OUTLET INTO WHICH THE COMPRESSIBLE FLUID AND YARN ARE REBOUNDED FROM THE ANVIL.

Int. Cl. D02g 1/20, 1/16, 1/12 U.S. Cl. 281.3 1 Sheet Drawing. 7 PagesSpecification A fluid jet injector device for use with yarn bulkingapparatus and other apparatus and adapted to separate the filaments of ayarn bundle and to increase drag tension on the yarn so as to assureconstant self-feeding of the yarn from its source to and through thedevice; to raise the temperature of the yarn to a crimp receptivecondition; and to convey the yarn to the bulking apparatus. The housingof the injector device has a passageway through which compressiblefluid, preferably heated, and the yarn travel, an anvil against whichthe compressible fluid and yarn collide and rebound causing increasedfilament separation and hence increased drag tension, and an outlet intowhich the compressible fluid and yarn are rebounded from the anvil.
